Practically anyone with a CAD program and a computer can operate the stress analysis packages available today. But does the Client get an answer to be counted on? Perhaps, or perhaps not. It depends very directly on the operator who is determining how the load is applied to the part, the mesh on the part, the boundary conditions, element types, symmetries, and attachment types. Experience is required to make these judgments correctly.
FEA is by far the most common form of numerical stress analysis performed today. We utilize ProEngineer’s Mechanica for complete 3-dimensional numerical computation of deflection, stress and strain.
